OPL3USB

OPL3USB is based on:

1. https://github.com/zhblue/y262lpt-v0.3b which is a clone of https://www.serdashop.com/OPL3LPT
2. OPL3 Duo! Board https://github.com/DhrBaksteen/ArduinoOPL2

OPL3USB is a board plug into usb works as a serial port (Arduino) and use a OPL3LPT (modified) as an OPL3 sound card for Dosbox-X.

This project can be a low cost replacement to SudoMaker's RetroWave if you already have an Arduino-nano or Arduino-UNO.

modified OPL3LPT means 3 lines added :

1. DB25-13--------VCC---------5V ( if your opl3lpt makes noise , use the original power line instead )
2. DB25-14--------IC----------YMF262-P3/YM3812-P3
3. DB25-15--------RD----------YMF262-P7/YM3812-P6

the clone verion above has already include these modifications.
